To fix issues with your Echo device not responding:

1. Make sure you're using the power adapter that was included with your device.
2. Make sure you have an active internet connection.
3. Check that your device isn't muted. The light indicator is red when your device is muted.
4. For devices without a screen: press the Action button to see if your Echo device responds.
5. To make sure that Alexa hears you, move your device away from walls, other speakers, or background noise.
6. Speak naturally and clearly.
7. Unplug your device and then plug it back in.
